January 2015 release of UK-DALE dataset and newly revised paper

[Jack Kelly]

We have just updated the UK-DALE dataset, and revised the UK-DALE paper.  Highlights:

• We now have five homes in the dataset (up from four in the last release)
• In each house we record both the whole-house mains power demand as well as power demand from individual appliances every six seconds.
  
• We also have 16 kHz recordings of mains voltage and current from houses 1, 2 and 5.  This data is available for download over FTP.  In total, we now have 4 TBytes of data (that's compressed)!
  
• House 1 has 655 days of recordings and 54 meters installed
• The new revision of the paper includes lots of plots describing the data (most plots produced with NILMTK.  And here are the scripts to produce the plots in the paper).
• The metadata has been updated to include some more information about each house (number of occupants, year the house was built etc).
